Knowledgeable, Efficient & Cost-effective QA/QC Inspection and Technical Training

BAY Technical Associates is a leading provider of both pressure equipment inspection services and API exam prep courses. We conduct Third Party QA/QC and Vendor Surveillance inspections, API / ASME Code inspection, Positive Material Identification testing, API / ASME consultation and expert witness services for our clients. Our inspection expertise is based on sound experience. Our founder spent over two decades as a pressure vessel inspector for a leading insurer of boilers and pressure vessels.

In addition, we also provide top-notch API training to those seeking to become certified inspectors. The BAY Technical series of API training seminars and courses were initially begun in the late 1970's. By 1996, the alliances we had formed provided a natural expansion into offering our full range of services to the pressure containing equipment industry.

Today, BAY Technical offers inspection services and training courses for the National Board, API 510, API 570, API 653 and API 580. Our API exam prep courses are offered nationwide, as well as in Canada. Thanks to this scope of services, and our commitment to quality and service, we have built up a loyal client base that includes various manufacturing and commercial sectors.

BAY Technical Associates is headquartered in Downingtown, Pennsylvania, just west of Philadelphia. We are conveniently located, within a 300-mile radius, to industries in the mid-Atlantic region, and near several major highways and airports that allow us to quickly travel to our customers and to their fabricators.

BAY Technical Mangement Team

Robert L. Yagle, (Bob) Founder and Lead Instructor

Robert L. Yagle, (Bob) Founder and President

Bob has over forty years experience in operation, maintenance, and repair of boilers as well as pressure vessel inspection, piping inspection and API training. After spending eleven years in the US Navy, as a Boiler Technician, Bob joined a leading insurer of boilers and pressure vessels. His tenure included such positions as Inspector, Authorized Inspector, Supervising Inspector, and Project Manager for Technical Training Mid-Atlantic Region. After twenty-two years with this firm, Bob launched BAY Technical Associates, Inc. in January of 1996.

Bob has been developing and presenting API Inspector Certification examination preparation seminars and courses since 1979. His results continually eclipse the national average. In fact, nearly 100 percent of Bob's students consistently pass their certification examinations on their first attempt.

Bob's unique training philosophy is to teach students how to use the API Codes and ASME Codes, not simply how to pass an examination. He tries to impress upon them just how critical pressure vessel inspection and quality is, and in doing so has positioned BAY Technical Associates as a national leader in pressure containing equipment-related training. Bob's vast knowledge of the boiler, pressure vessel, piping, and storage tank codes and fabrication has also made him an often-requested expert witness in court cases.

Why should I choose BAY Technical training?
BAY Technical Training consistently has industry-leading pass rates for our API Training Courses. You can see the specific numbers on our Training page. Many of our competitors offer a reduced rate to retake their course if you fail the exam. Why plan for failure? The BAY Technical training courses thoroughly prepare you to pass the exam the first time. Check our numbers.

What is your average class size?
Our average API test prep class size is between 6 and 15 people. We intentionally keep our API classes small because this allows for one-on-one help when needed and the participants get to know and help each other. Smaller class sizes allow for better interaction between the instructors and the participants, which in turn encourages questions.
